SAFETY DEVICE FOR AUTOMOBILES.

Application filed May 28, 1925. '-S.eria1 No. 33,579. g

' 'The presentinvention pertains to a safe ty device for automobiles designedrto prevent unauthorized access to the parts which 1 must be actuated in order to move the .vehicle. v

The particular object of the invention is the provision of a device of this character I 'again'making the circuit.

already stated.

including'a secondary two-way switch contained in a 'housing having a "locked door. The terminals of theswitch are connected to the ignition system and to an alarm device. The apparatus is so constructed that the switch may be actuated from the exterior of the'hou'sing to break the ignition circuit, but the door must be unlocked in order to permitaccess to this switch for This switch is secondary to a main two-way switch which is so connected that by movement of the switch arm thereof a circuit may be completed to the ignition system through the usual key switch on the dash board. In another position, the main switch makes a circuit through the arm of the secondary switch, requiring and enabling control through the secondary switch in the manner A further feature of the invention is the provision of a circuit adapted to pass through the lock to the alarm device. In this circuit is interposed a circuit maker which operates if the lock is tampered with when the proper combination of the lock is not set. By operation of this contrivance, the alarm continues tooperate until the lock is opened by some one who is familiar with the combination. 7 r i The housing also contains v a pair of switches controlling circuits operating electro-magnetic locks for the sections of the hood. These switches are accessible only from the interior of the housingso that the motor cannot be uncovered unless the door of the housing is opened. 7

I The device consists of a housing 1 (Figure 7) having an open side and an outwardly extending flange 2 formeda'long the ed 'es of this side. Against the flange is placed a.

substantially rectangular frame 3, and over showing thetheftalarm circuit is a detail transverse "section,

taining a cover 5 attached'to the plate by means of hinges 6. A pair of lateral memhere 7 secured to the underside of the cover plate support a switch panel 8 of insulating material as clearly shown in Figures 5 and 7 The inner face of the panel (Figure 13) carries a main two-way switch consisting of contacts 9 and 10 and a pivoted switch arm 11 adapted to engage either one of these contacts independently. The outer face of the panel (Figure 8) supportsi'another or secondary two-Way switch consisting'of a pair of bifurcated terminals or clips 12 and 13 between which is pivoted a switch blade 14.- on

a post 15. The terminals 9 and 10 extend through the panel as may be seenfrom Figures 3 and 13; At the outer'face of the panel, the terminal 9 'has'secured thereto a conductor 16 extending. to the usual igni tion switch on the dash board." Thus,'when this terminal is engaged by the switch arm- 11, the ignitionsystem may be set in operation by means of the usual-key on the dash board.

At the outer'face of the panel, a conductor; 17 leads from battery through terminal to the post Stillanother conductor l8j'extends from the clip to. the ignition system. When the switch arm 11 engages the terminal 10 and the plate let-isinserted in the clip 13, the ignition system is set into. 'operation -through the circuit made-by these connections.

This post is connected by; means, eta conductor $6 to another binding post on the outer taeevoi' the panel: and "thence to, asuitable" alarm device (not shown). bymea-ns of another conductor 48.

The-top; 4L4. of theangle piece M is provided with a'regulating screw 49. The free end of the arm 36 has attached thereto a spring conductor 50 which extends beneath thetop 41 1 and is adapted for engagement by the stem @Qandscrew 4&9. vAdj acent the sheath 40, a boss51 is" formed on the arm 7 1 This member contains a plunger 52 which is normally pressed outwardly by a spring The outer end or" the plunger has a notch 5 1 in which maybe received the stem as illustrated. in 1 Figure 12 for the purpose pointed out below-r The; plunger has a knob xten'dingithreughthe wall a OI; the. post and: sliidable :therein, whereby it may be pushed inwardly when ClGS1IBCl. 7

The inner face of the panel 8 supports a clip 82 which encloses, but does not engage, a finger 83 also supported by the panel. These members are secured to the panel by binding posts 84 and respectively which extend to the outer face of the panel as shown in Figures 3 and 15. The former post is connected to post 47 by a conductor 86 and the post 85 communicates with the switch pivot 15 through a conductor 87. .The switch arm 11 carries a blade 88, insulated therefrom, adapted to enter clip 82 and connect it to fingers83 when the arm 11 engages the terminal 10,

as illustrated in Figure 8.- In this manner a circuit is made between the battery connection 17 and the alarm conductor 48 when the arm 11 is brought into engagementwith the terminal 10.

WVhen the vehicle is to be parked, the driver applies the brake, opening the brake switch, and then presses the button-73 to move the switch blade 14 out ofthe clip 13 and into the clip 12. Although theignition circuit is thereby broken, a connection "is made between pivot post'15 and conductor 70. If the brake is now released in an attempt to steal the vehicle by; towing, the brake switch is closed whereby thefpivot post 15 is grounded t0 conductor 70 and the switch brake. Current is tapped at post 15 flowing through conductor 17 to the ground and through conductor 87, post 85, clip 82, finger 83, blade 88, post 84', conductor 86, post 47 and conductor 48 tothe alarm device. Since the battery and alarm are also grounded, the alarm will be actuated to indicate that the brake has been released. I

The springconductor 50 and connected parts serve to operate the alarm device when the lock is tampered with. This condition is shown in Figure 8. Assuming that the permutation discs have not been set in proper combination, rotation of the handle 58 will cause .the arm 36 to move downwardly in the manner already described. The tooth 41 will engage the edges ofthe disc and be stopped thereby and consequently cause the stem 42 to hold the free end of the conductor 50;Upon continued movement of the arm 37, the conductor will In the cover is mounted a properly protect his vehicle.

ground wire. 68. The stem 43 will be're v ceivedin the notch54 of the plunger to make this connection permanent until the plunger is withdrawn by pressure on the I stem 55. It will be noted that the-latter movement cannot be made until the cover" is opened, whereby the alarm continues to operate until such time.

' To the outer face of the panel 8 is secured a pair of spring arms 74 (Figure 3) having binding posts '75 attached thereto. binding posts are connected by conductors 76 to the electro-magnetic looks adapted to hold inclosed position the hood sections of the vehicle (not shown); The arms 7 4 pass beneath a conducting strip 77 to whichis also attachedthe arm 11 of the main switch. The spring arms are normally spaced from the strip, but maybe moved into engage mont therewith by pressure on buttons 78 of the insulating material carried-by themembers .74 and accessible from the inner side" of the panel. By operation-of these buttons 'which can be reached only when the door 5 to either" is open, a circuit may be completed one of the electro-magnetic locks.

In order to throw the door open when the 8 The i in engagement with the spring and the other end engaging the inner face of the door. .When the door is closed, as in Figure 5, the spring is under pressure. Therefore,

when the bolt is withdrawn, the door. is I thrown open'by virtue of this pressure.

It should be noted' that unless the per I mutation discs are set in a locking position it is impossible to close the door, thereby forgetting to protecting the owner against While a specific embodiment of the inventionhas been illustrated and described, it is to be-understood'that various alter-- ationsin the details of construction may be 'made without departing from the spirit of the invention as indicated by the appended claims.
